# physicalMetrics

The physical metrics associated with a scene.

```
var physicalMetrics: PhysicalMetricsConverter { get set }
```

## Discussion

Reading this value returns a `PhysicalMetricsConverter` corresponding
to the window scene associated with the environment’s reader. The
converter can convert point sizes into physical measurements of length,
and vice versa.

Reading this value is only supported in the body of a [`View`](/documentation/SwiftUI/View) or of
a type that inherits a [`View`](/documentation/SwiftUI/View)’s environment.
